Re: SQL UPDATE from Other File

Update TableA Set TableAFld1 = (
select TableBFld9 from TableB
where TableAFld2 = TableBFld1)
where TableAFld2 = TableBFld1

Pay attention that the inner select returns exactly one value ;-)

Betreff: SQL UPDATE from Other File


I'm losing my mind. Can someone give me an example of updating a
column in TableA with a value from TableB where a different column in
TableA matches a value in TableB? I want this:

Update TableA Set TableAFld1 = TableBFld9 where TableAFld2 is in
(select TableBFld8 from TableB)

Can I not do this? Do I have to join the tables instead? If so, how do
I specify an update with a join? TIA...
